With the Capitulation of Estonia and Livonia in 1710 the Swedish dominions Estonia and Livonia were integrated into the Russian Empire following their conquest during the Great Northern War. The Livonian nobility and the city of Riga capitulated on 4 July (O.S.) / 15 July 1710 (N.S.), Pernau (Pärnu) in August, and the Estonian nobility and the city of Reval (Tallinn) on 29 September (O.S.) / 10 October (N.S.). Russia left the local institutions in place and confirmed the traditional privileges of the German nobles and burghers, especially with respect to the Protestant faith. The land reform of the so-called reduction which had been introduced by the Swedish king Charles XI, and transformed many serfs to subjects of the Crown, was reversed.
